When forests are cleared or cut down it is called deforestation.

People remove forests for different reasons:

in order to make more room in cities for people to live;

to grow more food and raise livestock;

in order to make money and sell the timber.

So many forests are being cut down that it is making the earth sick, which is dangerous to all life on planet earth.

Industrial pollution damages plant growth in forests through acid rain, chemicals, and wastes in lakes and streams. Eventually the trees, plants and animals die.

Less forest plants means less oxygen and more carbon dioxide in the air. This imbalance threatens the air we breathe.

More heat from the sun is trapped on the surface of the earth, rather than being reflected back into space. This causes less rainfall and more drought. The earth is experiencing dramatic changes in its climate due to deforestation.

70 percent of earth's animals and plants live in forests. With deforestation, many animals and plants no longer exist (which is called being extinct) or threaten to become extinct as their habitats are destroyed.

How many forests are on the earth?

Before people began to cut down forests to build cities and create farmland, forests covered about 60 percent of the earth. That was a lot of trees, plants and animals. Over half the earth was covered with forests. Today there is only about one-fifth of the original forests remaining. Forests are being destroyed and it threatens all life on earth.
